See my profile (ACTUALLY TAKE IT IN!), I do not know your rig, just some mehanicals in it.
You should have bought a CJ!
No computer, '76-'86 long span for few mechanical changes, Choices CJ5, CJ7, CJ8 ! Even before that '41-'75 kept lots of "Proven ideas and parts!
Parts and aftermarket stuff is geared toward, a rig being around forever!
Parts are inexpensive and will be available forever.
BACK TO YOU---SAW YOUR QUESTION IDLE FOR A WHILE, I WAS HOPING ONE OF THESE MODERN GUYS WOULD ANSWER YOU.
BEING A JEEP FELLER, MYSELF. I FEEL OBLIGATED TO AT LEAST KEEP YOU FROM WEARING YOUR SHOES OUT.
I WILL GIVE YOU, WHAT I CAN, THAT "COULD" MAYBE HELP.
With stuff reving up and down + other stuff, leads me to believe that your computer is either getting bad input or no input from sensor(s) on your rig.
Sensors on your rig and others similar "most of the time" throw a code, when they are in "distress".
Sometimes the code alerts you thru "check engine light" or other lights....IF LIGHT WORKS!!!
Regardless, to get you a "possible" FREE diagnosis of your "computer throwing or storing a code".
Take him to Advance Auto or Autozone (some others) they will, if they can FIND CODES---OR STORED CODES!
Usually the "experienced employee" can tell you what to change, where it is, maybe more specifics on it. And sell you what you need for entire repair.
GET YOU A MANUAL WHILE YOU ARE THERE, read thru it like a novel, to learn about your rig, use it like a dictionary for your fixes....now and later!
Please reply with good news!
I'm Rootin' for you!
